Find all x $-$values for which the function in the given graph is continuous $($from both sides$)$ but not differentiable. Note that the graph is discontinuous at $\backslash ($ x$=0\backslash )$ and $\backslash ($ x$=36\backslash )$ and is continuous everywhere else in its domain.

A$.\backslash (\backslash$mathrm$\{$x$\}=\backslash )$

$($Simplify your answer. Use a comma to separate answers as needed.$)$

B$.$ There are no $\backslash ($ x $\backslash )-$values where the function in the graph is continuous from both sides but not differentiable.
